BUCKSTAY.

SPECIFICATION forming part of Letters Patent No. 621,576, dated March21, 1899.

Original application filed May 25, 1898, Serial No. 681,718. Divided andthis application filed September 28, 1898. Serial To aZZ whmn it mayconcern:

Be it known that we,WILLIAM LANY ON and JOSIAH LANYON, citizens of theUnited States, residing at Pittsburg, in the county of Oraw 5 ford andState of Kansas, have invented certain new and useful Improvements inBuckstays; and we do hereby declare the following to be a full,.clear,and exact description of the invention, such as will enable others toskilled in the art to which it appertains to make and use the same.

Our invention relates to buckstays for f u-rnaces.

The object of ourinvention is to provide a [5 buckstay especiallyarranged for use in connection with furnaces for smelting zinc in whichgas is used as a fuel.

Our invention is especially useful in connection with a zinc-smeltingplant, such as has been shown and described inour application, SerialNo. 681,718, filed May 25, 1898, of which this application is adivision.

The invention consists in the features, details of construction, andcombination of parts, which will first be described in connection withthe accompanying drawings and then particularly pointed ou-tin theclaims.

In the drawings, Figure 1 is a sectional view, partly in elevation, of abuckstay and its attached parts embodying our invention; Fig. 2, a frontelevation of the buckstay alone; Fig. 3, a topend view of the same; Fig.4, a front elevation of the buckstay with the air-pipe and the lower endof the gas-pipe in place, the damper-handle also being shown; Fig. 5, atop end view of the buckstay, showing the air-pipe and the damper-trod hin section; Fig. 6, a transverse section of the buck: stay on the line 66, Fig. 4; Fig. 7, a transverse section of one form of furnace providedwith a buckstay embodying our invention; Fig.8, a horizontal sectionthrough three buckstays, the two at the left embodying our invention,While the one at the right is of the usual form. In this view the valvesare shown in elevation and the gas and air pipes in section.

As our improved buckstay is particularly intended for use in connectionwith a smelt- 50 ing-furnace for metals such as zinc, we have (Nomodel.)

shown it in Fig. 7 in such connection, and will therefore describe it insuch relation as one example of its application in order to give a clearunderstanding of the advantages obtained by its use.

lar toFig. '7, A are retorts constructed in the usual manner with closedrear ends and open front ends, these retorts being set in a furnace insuch a manner as to slope rearward,

being in the present instance supported at the rear by a central wall Band at the front .by bearing-bars 13, each of which has its ends turnedoutward and riveted to buckstays B B Figs. 8 and 9, which extendvertically at intervals along the sides of the furnace and are tiedtogether in the usual manner by tierods 13 at the top and bottom of thefurnace. Certain of the buckstay's-in the present instance thebiickstays B -a1e provided with transverse openings or-holes 19 Figs. 1and 2, through which may be supplied air or air and gas to the interiorof the furnace. Suitable means for supplying either air, gas, or air andgas-to the furnace through these openings is provided, the means forsupplying air consisting in the present instance of vertical air-pipesF, one for each perforated buckstay B which air-pipes are each suppliedwith openings f opposite the corresponding openings in the buckstay.'The air-pipes F are connected to a main air-pipeas,for instance, thepipe F, Fig. 7located upon the top of the furnace and supplied with airfrom a suitable source, as a blast-fan F The means for supplying gas tothe furnace consists in the present instance of a series of verticalgas-pipes G, leading from a gas-main G, located, preferably, above thefurnace and supplied with gas from a suitable source. (Not shown.) Eachgas-pipe G is connected, preferably by suitable nipples g, Fig. 1, tothe respective air-pipe F at a point opposite the openings b in therespective buckstays B In order to control the supply of air to thefurnace, suitable valves are provided, preferably in the form of dampersH, Fig. 1,10- cated in the upper ends of the air-pipes F and controlledby hand-levers h, fulcrumed at h on brackets 7L2, secured to thebuckstays.

55 Referring to the drawings, and in particu- The supply of gas to thefurnace also is controlled by suitable valves, as shown at I, thesevalves being preferably located in the gaspipes G near their upper ends.

Meansfor controlling the-passage of air, gas, or air and gas through theopenings 11 in the buckstays B is provided, this means consisting ofvalve devices preferably constructed as follows: The outer ends of theopenings b in the buckstays B are enlarged to receive a valve K, havingwings 7a, which project into the respective openings, whereby the valvesare guided in their movements. To each valve is attached a stem or rodK, passing outward through the corresponding ai r-pipe' F and gas-pipe Gand provided with a suitable handle at the other end. The valve-stemsmay, if desired, be packed at the point where they pass through thegas-pipes by means of an ordinary packing-gland in as shown in Fig. 1;but this is not a necessity and may be omitted. y

The operation of our invention is as fol lows: The gas is allowed toescape into the furnace by first opening the valves I, one after theother, and then the valves K, the gas being lighted at the moment itenters the furnace through the openings Z1 in the buckstays B. Somelighted shavings, paper, or other combustible material being thrown intothe furnace, the gas is turned on and becomes ignited, whereupon the fanF is started in op. eration, after which a supply of air may befurnished to the gas-supply by moving the damper-levers h to open thedamper-valves H,.thus allowing the air-blast to pass down the pipes F,Fig. 7, where it unites with the gas entering the pipes F through thenipples g from the gas-pipes G. By suitably adj usting the damper-valvesH and the gas-valves I the desired mixture of air and gas is obtained inthe pipes F, and this then can be admitted at any desired rate to theinterior of the furnace by appropriately adjusting the valves Kbypulling out or pushing in the valve rods or stems K through the mediumof the handles 7c. The products of combustion escape through theopenings B into the stacks D D.

Having thus fully described our invention,

what we claim as new, and desire to secure by' Letters Patent, is

1. In a smelting-furnace, the combination, with a buckstay having aperforation extending transversely entirely through it, of an air-supplypipe in close contact with the buckstay and provided with an openingcommunicating with the perforation in the buckstay, and a valve arrangedto close the said perforation.

2. In a smelting-furnace, the combination, with a buckstay having aperforation extending transversely entirely through it, of an air-supplypipe in close contact with the buckstay and provided with an openingcommunicating with the perforation in the buckstay, and a valve withinthe perforation in the buckstay and arranged to close the same.

3. In a smelting-furnace, the combination, with a buckstay having aperforation enlarged at one portion to form a valve-seat, and anair-supply pipe in close contact with the buckstay and provided with anopening communicatin g with the perforation in the buckstay, of a valvelocated in the enlarged portion of the said perforation and arranged toclose against the valve-seat.

4. In a smelting-furnace, the combination, with a buckstay having aperforation and a pipe outside the buckstay and arranged to dischargeinto the perforation, of a second pipe outside the first-mentioned pipeand discharging into the latter, valves for controlling each pipe, and avalve in the perforation.

5. In a smelting-furnace, the combination, with a buckstay having aperforation enlarged at one portion, and a pipe outside said buckstayand arranged to discharge into said perforation, of a second pipe ontside the firstmentioned pipe and arranged to discharge into the latter,and a valve in the enlarged portion of the perforation.

6. In a smelting-furnace, the combination, with a buckstay having aperforation, and a pipe outside said buckstay and arranged to dischargeinto the perforation, of a second pipe outside the first-mentioned pipeand discharging into the latter opposite the perfora tion, a valve inthe perforation, and a valvestem 'connected'to said valve and extendingthrough both pipes.

7. In a smelting-furnace, the combination, with a buckstay having aperforation, an airsupply pipe and a gas-supply pipe, the interior ofeach of said supply-pipes communicating with the said perforation, of avalve in each supply-pipe for controlling it,and a valve arranged toclose said perforation.

8. In a smelting-furnace, the combination, with a buckstay having aperforation, an airsupply pipe and a gas-supply pipe, the interior ofeach of said supply-pipes communicating with the said perforation, of avalve in each supply-pipe for controlling it,and a valve within theperforation and arranged to close it.

In testimony whereof We affix our signatures in presence of twowitnesses.
